I use 2 sachets of VSL#3DS daily. I can't find a weight for them or on the box or packet. My drug insurance covers them, after I meet my huge deductible. It only covers DS, which means double strength. There are 900 billion bacteria with 8 strains of live, freeze-dried lactic acid lacteria.
Can you call her/him back and ask for more information?
FYI,
I was using 1 sachet daily until a few months ago. The increase has helped me stay off of antibiotics for my pouchitis and I am feeling better.
